供给侧改革视阈下中国一线城市动力研究

Research on motive mechanism of China's first-tier cities from the perspective of supply-side reform

基于我国8个一线城市(北京、上海、广州、深圳、杭州、成都、重庆和天津)2001—2015年面板数据,利用柯布—道格拉斯生产函数,从供给侧实证分析影响这些地区经济增长的动力因素,构建了经济增长回归模型。研究发现:对一线城市而言,资本存量弹性α是劳动投入弹性β的两倍,相比较于劳动投入,资本对经济增长的贡献较大;资本投入增长率呈现负值,经济增长动力因素不断从资本向技术转型;全要素生产率贡献率较低,但呈现递增趋势。研究所揭示的经济增长动力因素变化过程为我国一线城市供给侧结构性改革提供了理论依据,认为要素转换和制度改革是供给侧结构性改革的必经之路,创新是经济增长的内核动力。

Based on the panel data of eight first-tier cities in China（Beijing,Shanghai,Guangzhou,Shenzhen,Hangzhou,Chengdu,Chongqing and Tianjin）from 2001 to 2015,this paper uses the CobbDouglas production function to analyze the impact of these economies growth of the dynamic factors,and to build a regression model of economic growth.The study finds that for the first-tier cities,the elasticity of capital stock is twice the flexibility of labor investment,capital contribution to economic growth is greater than the contribution of labor investment;capital investment growth rate is negative,economic growth momentum factors from capital to technology;total factor productivity contribution rate is low,but showing an increasing trend.The change process of the economic growth motive factors reveal the theoretical basis for the structural reform of the supply side of the first-tier cities in China.It is considered that factor transformation and institutional reform are the only way of structural reform of supply-side.Reform is the core of economic growth.
